soluble molecules
Explanation:
Soluble molecules dissolve completely when mixed with water, hence forming a solution
Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms. Unicellular are one cells. Living organisms can be made of one cell or many cells. Those organisms that are one-celled are called 'unicellular' organisms. Some examples of these are amoebas, bacteria, and archaea.

Explanation:
Nitrogen fixation is a process of fixation of atmospheric nitrogen into forms of nitrogen that can be directly utilized by the plants like nitrates and nitrites. This process is conducted by the soil bacteria.
The farmers rotate the crops with legumes because the roots of legumes shows symbiotic mutualistic association with nitrogen fixing soil bacteria. The soil get rich with the nitrogen element necessary for growth of plants.
Answer: Option C) Triglycerides, long-chain hydrocarbon tails
Explanation:
Triglycerides are lipids, with three fatty acids (the same or different) having long hydrocarbon tails.
The hydrocarbon tails in triglycerides is the structural element that makes it insoluble in water as seen in the sample forming a separate layer on top of the water because it does not form hydrogen bonds with water molecules i.e hydrophobic
Thus, option C is the answer
